Title: Printer control system at time of detecting cover open
Inventor: FUKUSHIMA TAKASHI
IPC: B41J29/13
Filed: 1979-07-16
Abstract: PURPOSE: To improve the safety of an operator and an operation efficiency of the device, by a method wherein, in the serial impact printer, a cover open signal is detected by means of a sensor means when a safety cover is opened, and a printing motion of the printer is suspended rapidly.  
     CONSTITUTION: In the serial impact printer or the like equipped with a printing wheel and an input buffer memory, the cover open signal is detected by means of a cover opening-detecting sensor 11 when a safety cover is opened, and said cover open signal causes the printer to suspend operating in such a state as waits for printing, after a printing sequence at the said detecting time is over, or after, if a subsequent printing sequence starts, said subsequence printing sequence, which has already started, is complete. This causes the printer to rapidly suspend its printing operation, and thereby the safety of a operator is ensured. And only closing of the cover also permits restarting of the printing operation without a break from a former state that is before said suspension, and thereby an operation efficiency can be improved.
